You have been assigned to calculate the Weighted-Average-Cost-of-Capital for your firm, which has two sources of longterm capital. The company's marginal tax rate is 28%. First, there are 6,500,000 shares of common stock, which are currently selling for $153.12. Recently, the firm announced EPS of $12.64. You feel that it is reasonable to assume that earnings will grow at 1.65% into the future. Second, there are 6,000,000 shares of preferred stock outstanding that pay a perpetual (annual) dividend of $3.85, and are currently selling for $52.04. Third, there is an issue of 460,000 coupon bonds with a face value of $1,000, which pays 6.35% (annual) coupons, and mature in twenty-three years. These bonds are currently trading for $1,182.10. Estimate the implied return on the preferred stocks. (The answer is a percent, round your answer to two decimal places, e.g. 4.75)
